if they got involed in a minor event, they could have gotten involed for an important even.

How does that even make sense... They were not allowed to interfere in important ways directly against Sauron or Morgoth

In The Letters of J.R.R. Tolkien (Letter #156), Tolkien explains the Valar's diminished role during the Third Age:

"The Valar... were forbidden to interfere: the governance of the world was committed to the Younger Children [Men and Elves]."

It's cute you know how to google for the answer you wanted. Nowhere in the book does it say that. The eagles only fought the zagul at the end in the movies.

Even in your link the reference they give for that paragraph doesn't contain that info. As the eagles arrived the zagul were destroyed by Frodo destroying the ring.

The narrative returns to Gandalf and those outside the Black Gate. To the north, the Captains of the West foundered on the hills outside the Gate, surrounded by a dark, rolling sea of Orcs and Wild Men. Gandalf stood proudly, white and calm, with no shadow falling upon him. Suddenly, a great cry rose up: “The Eagles are coming!”[1] Out of the north arrived a company of great eagles, led by Gwaihir the Windlord. The will of Sauron faltered, and all the armies of Mordor quailed in terror. A great roar shook the hills. Gandalf cried in victory that the Ring-bearer had completed his quest, and that the reign of Sauron has ended.[2]

The eagles never attacked the nazgul to help frodo, nor were the five armies involved with the ring or sauron, nor was them helping the dwarves a pivotal moment for the survival of middle earth.
